RAILWAY-CAR .VENTILATOFL SPECIFICATION forming part of Letters Patent No. 304,848, dated September 9, 1884-. Application filed January l2, l1884. (No model.)

To @ZZ whom, it may concern,.-

Be it known that we, WARREN B. OUTTEN and WILLIAM E. JoNns, residents of St.Louis,

i Missouri, have jointly made a new and useful Improvement in Railway-Car Ventilators, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which-4 Figure l is a side elevation of a carin which the improvement is embodied; Fig. 2, a bottom view of the car; Fig. 3, a vertical longitudinal section of the car; Fig. 4, a vertical cross-section of the car; and Figs. 5, 6, 7, details, Fig. 5 being a side elevation showing one of the registers used in admitting the outer air into the interior of the car; Fig. 6, a plan of one of the ventilators in the floor of the ear, and Fig. 7 a vertical longitudinal section showing one of the outlets from thecar.

i The same letters of reference denote the same parts.

This improvement consists,mainly,in a" system of fines which are attached to or embodied in the car as follows: A main flue extends longitudinally in the car, and at its ends is connected with the interior of the car. Two series of branch flues are connected with the inain due. One series is at one end of the car and the other series at the other end of the car. These branch flues lead to or toward the sides of the car, and at their outer ends are open to admit and discharge air, as hereinafal'ter described. `These branch flues are inclined to the main flue, the branch passages at one end ofthe car being inclined in one direction and the branch passages at the other end of the car in the opposite direction, substantially as shown in Figs. l, 2, 3,where A represents a railway car of the usual description, saving as modied by the present improvenient.

the car, and C C represent the branch fines at the other end of the car. All these flues at one end connect with the main ilue, and at the other end are open to t-he outer air, and, as shown more distinctly in Fig. 2,the iiues C C andthe iin'es C C incline in opposite direction. Suitable registers, D D, may be used to shutoff the air from or to regulate its discharge into the iue B. Within the flue B, and at or toward each end thereof,a ventilator, E, is preferably inserted.

The action of the improvement as thus far described is as follows: Let the car be moving in the direction indicated by the arrow fr, Fig. 2., The outer air will then enter the branch iiues C G, as indicated by the arrows c c, and from these branch iiues C C the air will pass into the main flue B.l After entering the flue B it will pass along that iiue, as indicated by the arrow D?, Fig. 2, and from the (then) rea-r end of the flue B the air will be discharged into the branch iues Cy C', and from the passages C C the air-current is discharged into the outer air, as indicated by the arrow c c, Fig. 2. 4 The effect of this is to create a draft from the interior ofthe car into the due B, as indicated by the arrows al, and this last, named body of air is drawn with the current entering through the fines O C into the iiue C C', and in that manner discharged from the interior of the car. rlhe register D, when the car is moving in the direction named, is open and the register D' is closed. Vhen the car is moving in the opposite direction to that named, the operation of the lues O C is reversed-that is to say, the air then iiows from the interior of the car, as indicated by the arrows cs a, Fig. 3, into and through the outlet b into the flue B, and the outer air passes into the branch tlues C C and thence into the iiue B, and thence is discharged into the outer air through the branch flues C O. The car is then ventilated through the outlet b', in which case the register D is open and the register D is closed. Fresh airis supplied to the interior of the car through the passages F F. The inlets to these passages are at f f,.Figs. l, 4, and the passages are preferably extended upward to deliver the air into the interior of the car at the upper part thereof, the inlets to the interior of the car being-at f f', and the admission of the air being controlled by means IOO of the registers f2 f2, which, for convenience, are operated by the rod f3. One of these rods extends along each side of the car, and by means of it all of the registers on the side of the ear to which the rod belongs can be simultaneously operated. The branch lues C C', at their outer ends, should be suitably extended, and constructed to cause the outer air to readily enter those of the branch lues which are pointing in the direction of the movement of the car and the inner air to readily leave those of the branch flues which, for the time being, are pointing in the opposite direction to that in which the car is moving. To this end the flues may be shaped, as shown, for instance, at c2 c2 or c3 c3. The construction cZ is in effect an elbow, and while it is desirable to have the portion c" of the flue which is betweenthe elbow and the flue B inclined substantially as shown in Fig. 2, it is not essential that it should be thus inclined, for thebranch tlues will in a measure operate when the portion c" runs directly from the elbow to the main iiue. Ve think it desirable, however, to incline the portions c ct to the main iiue B at the angle shown in the drawings. The flow of the air from the interior ofthe car into the flue B is promoted by admitting the air through the `rlues F F into the interior of the car, and by means of the registers f2 ft the circulation of air through the interior of the car can be controlled.

NV e claiml. The combination, in a railway-car, of iiues B, C C, and C C', said flue B extending longitudinally in the car and at its ends connecting with the interior ofthe car, and said flues G and C connecting at one end with the iiue B and at the other end opening to the outer air, and the iiues C C and the iiues C C being inclined in opposite directions, substantially as shown and described, and for the purpose set forth.

2. rIhe combination, in a railway-canot ilues B, C C, and C G and the registers D D', said iiue B extending longitudinally in the car and at its ends connecting with the interior of the car, and said flues C and C/ connecting at one end with the iiue B and at the other end opening to the outer air, and the fluesC C and the iiues C C being inclined in vopposite directions, and said registers being adapted to open and close either end of said iiue B, as desired. substantially as shown and described. 3. The combi nation, in a railway-car, of .ues B, C C and C C and the inlet-iiues F F, said iiue B extending longitudinally in the car and at its ends connecting with the interior of the car, and said iiues C and C connecting at one end with the iiue B and at the other end open ing to the outer air, and the i'lues O G andthe iiues C C being inclined in opposite directions, substantially as shown and described.
